The vapor density of a gas is 11.2. What is the volume (in liters) occupied by of this gas at STP? — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

$\text{Molecular Weight} = 2 \times \text{Vapor Density} = 2 \times 11.2 = 22.4 \text{ g/mol}$. <br>$\text{Moles of gas} = \frac{11.2}{22.4} = 0.5 \text{ mol}$. <br>$\text{Volume at STP} = 0.5 \times 22.4 = 11.2 \text{ L}$.
